rust using nightly channel
Hi:
Can we use experimental features in nightly channel? There are many useful
features that can only be use in nightly channel, e.g. the Alloc api, since
arrow requires control over low level primitives such as memory allocation,
simd execution, etc.

Yes, so maybe we need a conditional compilation method so that the user can
choose.

My opinion is that we should continue to support Rust stable since there
are users who can only use Arrow if it works with Rust stable.
However, maybe it is possible to provide an API so that users can provide
their own allocators and in that case they could choose to use nightly?
It's a bit more work for us, but gives users more choice.
Also, SIMD and alloc are both going to be stabilized very soon anyway so we
might not have to wait too long.
Thanks,
Andy.
